On a draft invoice you can apply a discount — either a percentage or a fixed amount.
- Open the draft invoice.
- In the Discount card, choose % or a fixed amount and enter the value.
- Tap Apply. The summary shows the discount line and the new totals.
- Use Clear to remove it.
Good to know: The discount comes off before tax, so VAT is charged on the discounted amount — and it’s reflected correctly in CIS calculations too. It freezes into the invoice when you issue it.
Tip: A fixed discount can never push the total below zero.
